TODAY’S PATENT – ALTITUDE PROTECTION DEVICE

The Altitude protection device was invented by Andreas Reinhard, Wendelin Eglin on 2^nd September 2004, bearing patent number US20040168244A1

This present invention is an altitude protection device according to the invention for an acceleration protection suit operating according to the hydrostatic principle and having a plurality of liquid-filled veins consists of a bladder inserted in a pocket and consisting of an elastic plastic. A knitted spacer fabric, preferably consisting of monofilament material, is enclosed in the pocket. This fabric is non-compressible under the loads to be provided and thus defines a minimum volume in the interior of the bladder. The bladder is closed off or opened relative to the surrounding air in the aircraft cabin by means of a valve.

The object of the present invention is to provide a device which supplements an acceleration protection suit (referred to hereafter as a G-suit) and which, in respect of this G-suit, can afford an altitude protection which is effective for the instances mentioned, along with a negligible increase in mass of the G-suit. Furthermore, the outlay in technical and economic terms for this purpose is to be low.
